ActiveJob - log enqueued message only after the job was successfully enqueued

[cristianbica]

Currently if you try to enqueue the job with unserializable parameters you will see in the logs that the job was enqueued but you got an exception:

[72553d29-bd35-4e22-b0f7-b019df240aed] [ActiveJob] Enqueued Activejob::PerformLater::Job (Job ID: 6880ff6a-4558-4b1e-bef1-920b4229e280) to Sidekiq(default) with arguments: #<PaymentsService:0x007fc5cb4dc4c8>, "process", []
[72553d29-bd35-4e22-b0f7-b019df240aed] Completed 500 Internal Server Error in 54ms (ActiveRecord: 1.8ms)

  app/models/payment.rb:10:in `block in <class:Payment>'
  app/controllers/admin/base_controller.rb:16:in `create'

This PR moved the logging on the after_enqueue calback

This make sense..
I guess we need a changelog for this.
Also I would guess we will need to backport this to 4-2-stable right?

@arthurnn I don't see a need for a changelog entry.
About backporting I'm still not able to judge that so I'll just ask @rafaelfranca :)
